See, for example, /~https://github.com/quarkiverse/quarkus-pact/actions/runs/13383677293/job/37376521613 (the Pact ecosystem CI).
I am also seeing this locally.

1. cd observer-extension
2. ./mvnw clean install
3. cd ../weaver
4. ./mvnw clean quarkus:devyou'll see

It doesn't affect the app at all

In /~https://github.com/quarkiverse/quarkus-pact you'd need to update the Quarkus version first. I think @edeandrea's version should reproduce out of the box.

I've also seen this error in a really trivial app with no Pact extension, just a few @TestProfiles, but I was doing something else and assumed it was a dirty environment, so I just moved on and didn't make proper notes of what the app was like.

[aloubyansky]

Right, it can be reproduced in any project with continuous testing.

Thanks for the pointers!
